一种基于多路径的干扰避免协议研究

如何保证无线网络业务的连续可靠传输,成为多跳无线网络MHWN研究中亟待解决的问题。多路径路由作为实现无线网络可靠运行的有效手段,得到了广泛的研究。本文主要研究了MHWN中干扰避免问题,提出了一种适合MHWN的多路径路由算法,该方法具有较低的协议开销,通过网络干扰动态性检测获取遭受干扰最小路径,从而可有效提高网络抗干扰能力,并极大降低源重路由次数。文中详细阐述了协议的实现,并基于NS2对上述方法进行了较全面的仿真研究。结果表明该方法具有更好的路由抗干扰性能。

An Interference Mitigation Protocol Based on Multi-Path Routing

As the distributed and dynamic network architecture,the broadcast nature of wireless medium and stringent resource constraints of wireless devices makes MHWN(multi-hop wireless network)extremely attractive and vulnerable to malicious attacks.So how to ensure continuous network service becomes a critical problem especially in jammed situations.In this paper,interference avoidance mechanisms are well concerned.Then a proactive multi-path routing mechanism based on interference dynamic measuring is proposed to improve the MHWN performance under jamming.The proposed mechanisms need extra support in the form of routing interference entries to build higher robust anti-jamming paths in MHWN,while keeping the less reroute request times.Our evaluations based on NS2 show that the proposed mechanisms can provide robust anti-jamming paths for MHWN.
